About Stephen Sellick
As a nationally recognized leader in complex quantitative analysis of novel, unstructured problems in corporate litigation and public policy, Stephen Sellick brings a wealth of interdisciplinary crystallized intelligence and insight to board leadership. Leveraging his background in economics, professional services, risk management, and high-stakes litigation, Sellick brings value to boards of directors with his ability to quickly assimilate new information and apply systems thinking and shoshin (“beginner mindset”) to collaboratively identify and optimize the balance between risk and shareholder value maximization.As a consultant, Sellick is trusted by C-suite clients to provide counsel, analysis, and expert testimony for companies facing existential risks. After making partner at a prominent consulting firm, he founded Gnarus Advisors. Under his leadership, Gnarus was named as one of Consulting magazine’s “Seven Small Jewels” and recognized by Inc. magazine as one of America’s fastest-growing private companies.
